The guy with dark hair and scruffy moustache is Mikey from Mike Schlosky's Mikey's Life (also now discontinued); there's Camille the porcupine from Big Sandy Gilmore, the goth girl is Chloe from Good Times, and at far right is an early version of Chris Mann (aka Kid Charisma) from my own Everyday Heroes.
Tune in tomorrow for the exciting conclusion!
